It is over twenty five years ago, so I don't remember exactly. There was no internet fora back then to help, no known spares in the UK and it leaked!
Someone at work (I left that place in '88) machined the new graphite seal from a "huge" motor brush (talking here perhaps 1/2 megawatt motors - or more - could have been the donor) although it may have been a softer grade DC brush. I just cannot remember.
Most parts were re-used - the spring is there to maintain contact pressure on the sealing ring? The brush may well have been a worn out item, or a no-longer used item or even a new one - can't remember. I do know I have a couple of suitable brushes somewhere if I ever need to make another seal - just not rightly sure where, after all this time.
The waterproofing cap was a simple flexible cover/boot that fitted over a conduit pipe and the end was snipped off according to the size of the in-going electrical cable. I just used whatever was to hand at the time to get over the problem of a long-obsolete American made tractor in the UK.
It was a simple-tech solution to the current problem at that time. I worked at a large cement works and did have access to help and assistance for 'projects'.
Sorry but can't be any more help than that. I simply had a problem and worked around it the best way I could.
I do know I also replaced the phosphor bronze oil permeable bearings with sintered ones (leaks rather more oil through to the shaft than originally, I think) and the fan shaft may or may not have been machined very slightly to get over some pitting issues.
As I recall the back sides of the original fan shaft bearings were totally chock-a-block with solids which almost certainly were the cause of the bearing wear found and so the reason for the wear on the seal.

Today's Featured Article - Madison's County - by Anthony West. Philip Madison has been a good friend of mine for quite some time. He has patiently suffered my incessant chit chat on the subject of tractors for longer than I care to remember, and on many occasions he has put himself out, dropped what ever it was he was doing, to come and lend a hand cranking handles, or loading a find onto a trailer. Although he himself has never actually owned or restored a tractor, he was always enthusiastic and always around helping with other peoples projects.
